How do I get through the phone menu to a real live person?

GetHuman researchers routinely call this Costco phone number to document the phone system.
Here is our latest tip for weaving through the phone menu to get to a real person the fastest: Calling this Costco number should go right to a real human being
In fact, much of this information on this page is superfluous because this Costco phone number is a direct line to a human being. The line is well-staffed and you should anticipate a very short wait on hold or none whatsoever, as long as you are calling during business hours.
We don't know of any phone menus you would encounter when calling either.

What are the hours and when should I call?

Costco operates the call center for this 866-861-0450 phone number Mon-Fri 5am-8pm PT. The short answer is that you should call on a Wednesday. This observation and the following section are based on analysis of a sample set of 9,697 calls made in the last 90 days using our free, web-based phone (see above).
An important note: busy times vs hold times vs best time to call
When we refer to busy or less busy times, we are talking about the volume of calls. The busiest times are when the most people are calling this Costco phone number (least busy times have fewer people calling). This high call volume does not necessarily mean that you will have a long hold time when you call. Companies like Costco staff their call centers differently based on the time of day and day of the week, so you may experience a shorter wait on hold at the busiest of times. When we refer to the best time to call, we are referring to the optimal combination of lower call volume and shorter wait times.

The least busy time to call

The least busy day to call Costco is Wednesday. The most busy day to call is Thursday. Again, this is based on a sample of 9,697 calls made with our AI-powered, web-based phone in the last 90 days.

The shortest wait on hold

We measured the shortest hold times to be on Tuesday. The longest wait in the queue on average occurs on Friday.

The best time to call

In summation, the best day to call Costco is Wednesday. This is not the day with the shortest wait on hold in the phone system, but we still recommend it for its ideal combination of low call volume and short hold times. Plus we believe that Costco staffs the call center well on Wednesday.
Once again, please put this information in perspective because this phone number has no phone menu or long waits. It generally gets picked up right away if calling during their opening hours. If there is any way, it will typically be very short.
